InactiveUS20060284965A1Eliminate feed errorPrevent variationRecording apparatusPrinting mechanismsRotary encoderEngineering
A printer comprises a feed roller to which driving force is transmitted from a motor via a reducer. While the feed roller moves a recording paper, an image is recorded by a line print head one line by one line. The feed roller is provided with a rotary encoder. A controller counts encoder pulses (measured EP) of the rotary encoder to measure an actual feed amount of the recording paper. Whenever five lines are recorded, the measured EP is compared with predetermined reference encoder pulses to detect a feed error of the recording paper. In case that slipping or the like occurs on the reducer, delay in feeding the recording paper is caused. A printing cycle of the next five lines is adjusted so as to eliminate the feed error. In this way, a printing length of one frame is adjusted to a target printing length.

An ignition timing control system for internal combustion engines, which is capable of preventing occurrence of variation in engine speed and vibrations which can be caused due to variation in combustion state between the cylinders, to thereby improve drivability. The ECU 2 of the ignition timing control system 1 calculates a statistically processed value Pmi_ls#i according to the in-cylinder pressure Pcyl#i, and calculates an averaging target value Piav_cmd by weighted averaging of a minimum value Pmi_ls_min1 and a second minimum value Pmi_ls_min2 within a predetermined range of the statistically processed value. The ECU 2 calculates a correction value DIGCMP#i by performing a limiting process for setting the optimization correction value DIGOP#i for control of the ignition timing to a limit value on the advanced side, on the averaging correction value DIGPIAV#i for causing the statistically processed values Pmi_ls#i to follow the averaging target value Piav_cmd, such that the statistically processed values Pmi_ls#i becomes maximum. The ignition timing IGLOG#i is calculated for each cylinder based on the correction value DIGCMP#i.

Control device for internal combustion engine
InactiveUS20110126803A1Prevent variationStable controlElectrical controlInternal combustion piston enginesExternal combustion engineIgnition timing
A control device for a spark-ignition internal combustion engine that sets ignition timing based on a target value of a predetermined combustion-related parameter correlated with a combustion state and operates an ignition device in accordance with the ignition timing thus set. The control device calculates an actual value of the combustion-related parameter from an output value of the cylinder pressure sensor and feeds back the calculated value of the combustion-related parameter to the setting of ignition timing. Further, in parallel with the above processing, the control device calculates a value of a predetermined combustion variation parameter correlated with the magnitude of combustion variation from the output value of the cylinder pressure sensor. If the calculated value of the combustion variation parameter deviates from an allowable range of the combustion variation, the control device stops the feedback of the calculated value of the combustion-related parameter.
